Manna in the Desert and the Bread of Life
Old Testament: Exodus 16:14-15
And when the children of Israel saw it, they said one to another: Manhu! which signifieth: What is this! for they knew not what it was.
New Testament: John 6:49-51
Your fathers did eat manna in the desert, and are dead. ... I am the living bread which came down from heaven.
The connection
Christ draws this contrast Himself in the Bread of Life discourse: manna sustained the body for a day and its recipients still died, but the true bread from heaven gives life everlasting. Points directly to the Eucharist.
Moral sense
Depend on God daily; manna could not be hoarded, and neither can grace.
Anagogical sense
The eternal banquet where hunger itself finally ends.
Warrant
Checked in the Greek: artos and eremos are shared, the bread named at Exodus 16:15 in the Septuagint and at John 6:50 and 6:51, in the desert at Exodus 16:14 and John 6:49.
